A centrifuge is often used for astronaut training. A simplified version is sketched in Figure P3-22, in which a cockpit is rigidly attached to an arm that is driven by a motor. If in a particular test, starting from rest, the driving motor supplies a constant angular acceleration of 0.5 rad/s^2, and the distance from the astronaut's navel to the rotation axis is 10m, find the acceleration of the astronaut's navel as a function of time (with respect to ground). Note that gravity acts. The reference frames defined in Figure P3-22 are as follows: OXYZ is fixed to ground; Oxyz is fixed to the arm.

Where did you get the 3 from for the distance of q?

A piston engine in which the bore and stroke are of equal dimension is referred to as a "square engine". An 8-cylinder square engine has a displacement of 305 in3. What is the bore and stroke? Round to the nearest thousandth of an inch. "bore" is the diameter of a cylinder, and "stroke" is the height of a cylinder (the distance the piston travels in one stroke). You will need the formula for the volume of a cylinder to solve this problem.

Please solve it correctly , Don't Use Ai tool. (1) A twist drill bit is used to drill a hole of diameter 2.0 at 4578.1 rpm at a feed rate of 2.5 in/min. Calculate the MRR in in^3/min. Take "pi" = 3.14. Round your answer to the nearest tenth.
